Surgical Outcomes and Predictive Factors in Patients With Detrusor Underactivity Undergoing Bladder Outlet Obstruction Surgery / 대한배뇨장애요실금학회지

Purpose@#This study was conducted to evaluate the efficacy of bladder outlet surgery in patients with detrusor underactivity (DU) and to identify factors associated with successful outcomes. @*Methods@#We conducted a retrospective review of men diagnosed with DU in urodynamic studies who underwent bladder outlet surgery for lower urinary tract symptoms between May 2018 and April 2023. The International Prostate Symptom Score (IPSS) questionnaire, uroflowmetry (UFM), and multichannel urodynamic studies were administered. Successful treatment outcomes were defined as either an IPSS improvement of at least 50% or the regaining of spontaneous voiding in patients urethral catheterization prior to surgery. @*Results@#The study included 93 male patients. Men diagnosed with significant or equivocal bladder outlet obstruction (BOO) experienced significant postoperative improvements in IPSS (from 20.6 to 6.0 and from 17.4 to 6.5, respectively), maximum urine flow rate (from 5.0 mL/sec to 14.4 mL/sec and from 8.8 mL/sec to 12.2 mL/sec, respectively) and voiding efficiency (from 48.8% to 86.0% and from 61.2% to 85.1%, respectively). However, in the group without obstruction, the improvements in IPSS and UFM results were not significant. The presence of detrusor overactivity (odds ratio [OR], 3.152; P=0.025) and preoperative urinary catheterization (OR, 2.756; P=0.040) were associated with favorable treatment outcomes. Conversely, an unobstructed bladder outlet was identified as a negative prognostic factor. @*Conclusions@#In men with DU accompanied by equivocal or significant BOO, surgical intervention to alleviate the obstruction may enhance the IPSS, quality of life, and UFM results. However, those with DU and an unobstructed bladder outlet face a comparatively high risk of treatment failure. Preoperative detrusor overactivity and urinary catheterization are associated with more favorable surgical outcomes. Consequently, active deobstructive surgery should be considered for patients with DU who are experiencing urinary retention.

Assessment of quality of life of oral cancer patients after reconstruction with radial forearm free flaps / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate the quality of life in patients who had resection of oral cancer and reconstruction by radial forearm free flaps.</p><p><b>METHODS</b>Quality of life of 49 patients was assessed by means of the 14-item oral health impact profile (OHIP-14) and the medical outcomes study-short form-36 (SF-36) questionnaires 12 months after operation.</p><p><b>RESULTS</b>Forty-one questionnaires were collected (84%). SF-36: the highest-scoring domain were physical role (92.9 ± 2.6) and bodily pain (82.6 ± 5.7), the lowest-scoring domain were vitality (61.5 ± 9.1), followed by role emotion (64.9 ± 6.8) and social functioning (65.2 ± 8.2). OHIP-14: the best-scoring domain were handicap (37.1 ± 15.1) and psychological disability (45.7 ± 11.9), the best-scoring domain were physical pain (64.2 ± 11.7) and functional limitation (61.9 ± 12.9).</p><p><b>CONCLUSIONS</b>Radial forearm free flaps for reconstruction of oral defects after cancer resection could significantly influence the patients' quality of life.</p>

Efficacy and significance of various scores for pneumonia severity in the management of patients with community-acquired pneumonia in China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Community-acquired pneumonia (CAP) remains one of the leading causes of death from infectious diseases around the world. Most severe CAP patients are admitted to the intensive care unit (ICU), and receive intense treatment. The present study aimed to evaluate the role of the pneumonia severity index (PSI), CURB-65, and sepsis score in the management of hospitalized CAP patients and explore the effect of ICU treatment on prognosis of severe cases.</p><p><b>METHODS</b>A total of 675 CAP patients hospitalized in the Second Affiliated Hospital of Zhejiang University School of Medicine were retrospectively investigated. The ability of different pneumonia severity scores to predict mortality was compared for effectiveness, while the risk factors associated with 30-day mortality rates and hospital length of stay (LOS) were evaluated. The effect of ICU treatment on the outcomes of severe CAP patients was also investigated.</p><p><b>RESULTS</b>All three scoring systems revealed that the mortality associated with the low-risk or intermediate-risk group was significantly lower than with the high-risk group. As the risk level increased, the frequency of ICU admission rose in tandem and LOS in the hospital was prolonged. The areas under the receiver operating characteristic curve in the prediction of mortality were 0.94, 0.91 and 0.89 for the PSI, CURB-65 and sepsis score, respectively. Compared with the corresponding control groups, the mortality was markedly increased in patients with a history of smoking, prior admission to ICU, respiratory failure, or co-morbidity of heart disease. The differences were also identified in LOS between control groups and patients with ICU treatment, heart, or cerebrovascular disease. Logistic regression analysis showed that age over 65 years, a history of smoking, and respiratory failure were closely related to mortality in the overall CAP cohort, whereas age, ICU admission, respiratory failure, and LOS at home between disease attack and hospital admission were identified as independent risk factors for mortality in the high-risk CAP sub-group. The 30-day mortality of patients who underwent ICU treatment on admission was also higher than for non-ICU treatment, but much lower than for those patients who took ICU treatment subsequent to the failure of non-ICU treatment.</p><p><b>CONCLUSIONS</b>Each severity score system, CURB-65, sepsis severity score and especially PSI, was capable of effectively predicting CAP mortality. Delayed ICU admission was related to higher mortality rates in severe CAP patients.</p>

Post-coital gross hematuria: an unusual presentation of benign prostatic hyperplasia / 亚洲男科学杂志(英文版)

<p><b>AIM</b>To describe an unusual symptom of benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>A patient presented to our urology clinic having experienced post-coital gross hematuria for 2 years. He had not experienced lower urinary tract symptoms (LUTS). A series of examinations were performed to determine the source of bleeding.</p><p><b>RESULTS</b>The prostate was defined as the active bleeding source responsible for the patient's post-coital hematuria. Endoscopic fulguration did not alleviate the symptom. The use of dutasteride, a dual inhibitor of 5alpha-reductase, solved the problem.</p><p><b>CONCLUSION</b>This study reports for the first time that post-coital gross hematuria is one of the clinical presentations of BPH, which can be successfully treated with 5alpha-reductase inhibitor.</p>

Isolated posterior urethral injury: an unusual complication and presentation following male coital trauma / 亚洲男科学杂志(英文版)

We describe an unusual complication of coital trauma in a 29-year-old man who presented with a 3-year history of hematospermia and post-coital gross hematuria. Using urethroscopy under a semi-tumescent penis, an isolated urethral injury with active bleeding was detected at the prostatic urethra. The patient was successfully treated with transurethral fulguration. We suggest that isolated posterior urethral injury is one of the causes of male coital trauma, which might be asymptomatic when the penis is flaccid but show symptomatic bleeding when the penis is erect.
